I'll be doing a talk about FreeDV at Pacificon 2021 on Saturday, October 16th at 2pm. In addition, there'll be a FreeDV booth where people can ask questions and get more information about the mode. Come join us! More information about Pacificon is at http://pacificon.org/
BTW, if you're interested in helping staff the booth that weekend, please contact me off-list.
